The All Japan Senior High School Cultural Festival is a cultural festival by high school student representatives from all prefectures held in early August every year since 1977. The general opening ceremony and parade are held on the first day and the following four days see stage presentations and exhibitions in 19 different categories as well as special co-sponsored categories from the hosting prefecture. Some categories hold their own contests and provide students with opportunities to hear comments and participate in cultural exchange events. Prefectures take turns hosting the festival. 20,000 high school students participate from all over Japan and the number of visitors reaches 100,000 including local citizens.

Every year, high school students from three countries are invited to attend the All Japan Senior High School Cultural Festival. They participate in an opening ceremony and parade as well as an international exchange with local high school students.
